Don’t throw out good eggs just because they have passed the marked expiration date on the carton. A simple at-home test can tell you if the eggs in your fridge are truly expired: Fill a large bowl with water and carefully lower the eggs in. A very fresh egg will immediately sink to the bottom and lie flat on its side. This is because the air cell within the egg is quite small. The egg should also feel heavy.
As eggs start to lose their freshness and more air enters, they will begin to float and stand upright. The smaller end will sit on the bottom of the bowl, and the broader end will point toward the surface of the water. The egg will still be good enough to consume. If the egg floats in the water and does not touch the bottom of the bowl at all, throw it out â€“ it’s most likely a bad egg. Bad eggs will also feel light in weight and have a pungent smell.
Here’s a great trick for making hard-boiled eggs: Place eggs in a heavy saucepan and cover with cold water. Bring to a boil, then turn off heat, cover and let sit for 13 minutes. Rinse eggs in cold water, then eat. Hard-boiled eggs will keep in a refrigerator for up to 3 days.
